A few months ago i made it so that my site could only be viewed from my IP. I reverted the changes (i think) but now parts of my website do not display properly to other IP's (not even on the server computer itself!). CSS and images are missing and sometimes the page is even blank. Oddly the main page of the site displays fine to everyone else, but most php links display as blank pages.

Any idea what's happening? I'm pulling my hair out over this, i spent 5 hours straight on it with no results.
